Wine puts up a classy front. But, according to new research, that red, and that white, have a dirty little secret: they've got more booze in them than they're telling you.
A new study published in the Journal of Wine Economics has confirmed that wineries may be bending the truth on just how much alcohol is in that bottle. Researchers looked at data collected from The Liquor Control Board of Ontario, which included more than 100,000 observations of wines tested between 1992 and 2009. They measured the advertised alcohol levels in wine by volume, against the actual alcohol levels.
The data showed that close to 60% of wine samples had a higher alcohol content than what was advertised. On average, the alcohol content was about 0.39% higher in Old World wines and 0.45% higher in New World wines. But, some wine regions showed larger discrepancies than others. For example, Chilean reds and whites, Spanish reds, and American whites, were among the wines with the largest margin of error.
